We experimentally demonstrate a three-dimensional (3-D) optical code-division multiple-access (OCDMA) transmission system that encodes data on time, wavelength, and polarization. Such a system may be… (More)

We show theoretically and experimentally the relationship between a signal's degree of polarization (DOP), all-order polarization mode dispersion (PMD), and the optical spectrum (and hence the data… (More)

We experimentally demonstrate the existence of an optimal decision threshold in an optical code-division-multiple-access (O-CDMA) system and show its relation to the number of active users. Our… (More)

We propose and demonstrate two novel techniques for 10 Gb/s polarization-mode-dispersion (PMD) monitoring for NRZ signals that use a regenerated RF clock tone as a monitoring signal. Our techniques… (More)

Tunable pulse-width management is one of the efficient methods to enhance the robustness of return-to-zero (RZ) data formats for long-haul transmission systems. We demonstrate both single channel and… (More)

We demonstrate a simple technique for polarization-mode-dispersion (PMD) monitoring that is insensitive to chromatic dispersion (CD). By monitoring the extracted radio-frequency clock power from the… (More)

We demonstrate a technique for 10- and 40-Gb/s chromatic dispersion monitoring for carrier-suppressed return-to-zero (CSRZ) signals using the radio-frequency (RF) power at the bit rate frequency (the… (More)

We propose and demonstrate a new type of degree-of-polarization (DOP)-based differential-group-delay (DGD) monitor using an optical filter such that the DGD monitoring range and DOP dynamic range are… (More)
